ZF 4644.103.070 OUTPUT for WG200 | OEM Genuine Part

Overview

The ZF 4644.103.070 OUTPUT for WG200 is a critical driveline component engineered to transfer rotational force from the transmission’s planetary gearset to the output shaft flange. Positioned at the rear of the WG200 series housing, this OEM genuine part ensures precise torque delivery and alignment under heavy-duty industrial loads. The SKU 4644.103.070 is manufactured to ZF’s original specifications, guaranteeing a direct fit and long service life. When paired with a robust TRANSMISSION HOUSING, this output assembly maintains structural integrity during high-stress operations such as construction, mining, and material handling.

Symptoms of Failure

• Oil seepage around the rear seal: A worn output shaft bearing or damaged sealing surface often leads to fluid migration, visible as drips or wetness near the transmission tail.
• Vibration or driveline shudder: Excessive play in the output splines or bearing race causes noticeable shaking during acceleration or deceleration, especially under load.
• Intermittent gear engagement loss: If the output shaft cannot maintain concentric rotation, the transmission may momentarily slip out of gear, triggering fault codes in electronic controls.
• Metallic debris in transmission fluid: Spalling on the output gear teeth or bearing surfaces introduces fine metal particles, detectable during routine oil analysis.

Technical Specifications

Compatibility

This output component is specifically designed for the ZF WG200 series, including models WG180, WG200, and WG210. It directly replaces the original factory-installed part in TRANSMISSION HOUSING assemblies built after 2010. For installations requiring a different output flange pattern, verify compatibility with the ADAPTER plate and ensure the TYPE PLATE matches your transmission’s serial number. The 4644.103.070 is not backward-compatible with older ZF 4HP or 5HP series without significant housing modifications.
